Abstract
A metal mold centering and clamping device in a tire vulcanizing machine has hydraulic cylinders each having a piston rod equipped with a non-directional bearing at its top portion. The cylinders are mounted on a vulcanizing machine frame close to an outer circumference of a metal mold. An outside portion of a centering member is connected to the vulcanizing machine frame via parallel links to form a parallel linkage, and a bottom portion of the same centering member is connected to the piston rod via a link. On the inside of the centering member and on the outer circumference of a lower metal mold are respectively formed centering surfaces opposed to each other. In addition, at an upper portion of the inside surface of the centering member is formed a clamp claw adapted to be engaged with the edge of the lower metal mold.
